those are the bars i have on my k4 750, i went to those from a set of 10 degree tomaselli clip ons, then a set of the laverda adjustable clubmans. they allow me to ride for more than 45 minutes or so at a time and still be able to walk upright after a ride. it took a few miles to get used to not crouching over like a monkey guarding his nuts, but the extra length of these bars over the clip ons or laverda adjustable clubmans makes for better leverage, MUCH easier sitting position too. it also doesnt look too odd having the airtech cr750 styled seat and viper fairing and best of all i can spend hours on the bike and still be able to move later that day.
